Mid-Range OCTEON Multi-Core MIPS64 Processor Exceeds 40,000 Linux iSCSI IOPS-to-Disk and Single/Dual-Core OCTEON Processor Delivers 60MB/s NAS Performance

Cavium Networks' OCTEON Multi-core MIPS64 and the recently announced OCTEON Multi-core Storage Services Processors (SSPs) provide market-leading performance for network storage applications. The OCTEON processor family delivers two to four times more compute cycles versus many alternatives and integrates advanced hardware acceleration for RAID, compression, de-duplication, security and iSCSI. The OCTEON family scales from low-end solutions to very high performance SAN/NAS systems, providing a flexible, software-compatible platform across a broad range of price and performance points. Key OCTEON family features include integration of 1 to 16 MIPS64 64-bit cores, storage application acceleration, an array of high-speed input/output interfaces, Gigabit Ethernet ports, DDR2 memory controllers and innovative data protection mechanisms.

Cavium is demonstrating three performance benchmarks at Storage Network World 2007, targeting a range of different storage equipment designs:

1)  Enterprise-class NAS and SAN: This demonstration consists of a 4-core
    OCTEON Plus CN5830 processor in a 1U appliance from Movidis running Linux
    with the iSCSI Enterprise Target (IET) stack connected to SAS drives and
    serving over 40,000 iSCSI IOPS-to-Disk. One 16-core OCTEON can process up
    to 160,000 iSCSI IOPS-to-Disk or 640MB/s using standard Linux. Encryption
    can be enabled with line rate performance. This performance highlights
    OCTEON's leading performance, low cost and low power capabilities for
    Enterprise storage OEM equipment.

2)  Data-center Storage and Solid State Disk Solutions: This demonstration
    shows a 16-core OCTEON Plus CN5860 processor running Linux and performing
    over 2 Million virtual I/O operations per second (IOPS), which is 3x to 10x
    the performance of several deployed alternative processors. This showcases
    OCTEON's extreme IOPS processing power which is useful for large, data-
    center disk arrays as well as emerging solid-state-disks (SSD) that require
    significantly higher IOP processing compared to current hard-disk
    solutions.

3)  SMB/Home NAS: The third demonstration consists of a single- and dual-
    core OCTEON processor running Linux and Samba server connected to 4x SATA
    drives delivering 60MB/s of read and 40MB/s of write performance. OCTEON
    also achieves the same level of performance with RAID 5 for higher
    reliability designs. OCTEON single- and dual-core processors deliver OEMs
    with a low-cost, high-performance NAS reference design for Home and SMB
    markets.
